To all whom it :may 'concer-n Be it known that. Anoi'm: CAMPBELL, acitizen ofthe United States, residing at Chi cago, in the county ofCool; and Sta/tc of Illinois, have invented a certain new and usefulImprovement in Dump-Cars, of which the following is e full, clear,concise, and exact description, reference being had to the accompanyingdrawings, forming e. part of this specification.

My invention relates to improvements in railway car noni-traction eobject of my invention is to provide a. railway car of comparativelycheap and light construction, and yet of great strength, and one capableof -eiiid\iiiiig the severe shocks of service.

Certain features of my invention herein have been divided out and fornithe subject matter of divisional applications, ripper'- tively SerialXo. 720.149. and Serial Xo. ln in v 1 application herein confine myclaims to i 720,150, filed september ifi, i912.

the hopper structure, whereas in my co pendin applications the claimsare particiilary directed to the iiiiderfiainingr of a car and to otherfeatures relating to car construction.

accomplish this object may be used in contlie central longitudinalhopper sheet, 17 a transverse hopper sheet` 13 the car doors, 1S thedoor in its open position.

l) a pivot attachment of the door mechani n to the door 11:5. 3

are connectingrods which are used for oiirating the car doors 1S inconnection with the lever 21 borne iipon the shaft 22, wliithjoiiriialed in suitable bearings 23, and operated by ratchet 24.

25 are door hinges rigidly attached by suitable means at the upper edgesof the door 18. The said hinges have :in angle or turn so that the bladeof the hinge is substantially at right angles with the door 18.

liacli door opening adapted to be closed by a door 1S has adjacent eachside one of the transverse hopper siicets 17, each transverse hopperslicet being,r substantially at right angles to the 'upper edge of thedoor 1f, which door is adapted to swing transwisely of the cai'. Thehinges 25, there be ing preferably one at either end of the upper c-flgcof cach door 18, are attached to the transverse hopper sheets.preferably on the l oiitcr face 45 thereof ivitli reference to thencction with different forms of railway cars. i

invention, and have chosen for such description a cai commonly known a"ballast car, though it will be understood that by making this specificdescription in comico tion with a car of thisl type I do not intend tobe limited thereto, as it will be readily apparent that the broadprinciples of my invention are readily applicable to many typzes ofrailroad cars.

eferring to the drawings Figure 1 is a elevation of substantiallyone-half of `ad car embodyin'gmy invention, Fig. ian view of the same,Fig. 3 is a cross v"alien on line 3, 3 of Fig. 2, Fig. 4 section takenlongitudinally of the car ci the transverse hopper at. line lE 4, ofFig. 2, showing the method of attaching the hopper doors and hingebiitts. Referring to 'the drawings 10 is a car body, 11 the side of thecar, 12 a hopper bottom, 13 the end floor of the car, 14 the end of acar, l5 the end sill of a car, 16

adjacent door opening. ln preferable construction a hinge butt 27 isemployed for siicli attachment. the same being secured to thetransvcrsil hopper sheetl by the rivets *29, 28, ond the hinge beingplvotcd to the` By means of the angle provided iii the hinge and byreason of the. attachment of the hinges; to the transverse hopper sheetsl ain enabled to provide a door .vliich upon openinf,r in dischargingthe load tends in iii opening movement to elevate and allow thedistribution of the discharging load toward the renier of the track.

29 is a single center sill extending longitudinally of the car with itsends passing preferably to the forward cdgesof the body bolster 3() ofthe car. though the saine may be extended to the draft. devices. andliaving a vertical recess 3l on its under surface for the reception ofthe king pin nul. SliDWlt in the drawings.

39 are angle irons vertically disposed at the inner ends of the andfloor of the car forming the slots 40 for tlic reception of partitioningmeans between the level and l my invention to one type of car.

car, and provided with oor operating mechathe entire car in service forthe carrying of a commodity I have provided a. means at the ends of thecar by forming the slots 4l between the end 14 of the car and thevertieally arranged angle irons 42, which are attached by suitable meansto the sides of the car, as illustrated in Fig. 2.

I have thus described the application of I claim: L

1. In a dump car, the combination of a hopper having longitudinal andtransverse hopper sheets, car dogors associated therewith adapted toswin transversely of the nism, of angular hinges secured to each doorand pivoted to the transverse hopper sheets.

2. In a dump car, the combination of a hopper having longitudinal andtransverse hopper sheets with hopper doors associated therewith, saiddoors being provided with door operating mechanism adapted to swing thesamel transversely of the car, and each attached to the hopper byangular hinges pivoted to the transverse hopper sheets, whereby uniformcentral distribution of the load from the car is secured.

3. In a. dump ear, the combination of a hopper having longitudinal andtransverse hopper sheets, hopper doors associated with said hopper, andprovided with door operating mechanism adapted to swing said doorstransversely of the car, each of said doors being attached to angularhinges, each of said hinges being pivoted to the transverse hoppersheets, whereby the said doors upon opening tend to elevate andcentrally distribute the load of the car.

4. In a dump car, the combination of a hopper with openings betweenlongitudinal and transverse hopper sheets, with hopper doors arrangedlongitudinally of the car, cach of said doors associated with dooroperating mechanism, and each provided with hinges angleswvith the door,the said hinges being pivoted to the transverse hopper sheets, wherebyupon opening the said doors elevate and centrally distribute the load.

5. In a dump car, the combination of a car body having a door opening,longitudinal and transverse hopper sheets forming said opening, a doortherefor, hinges connected to the door, and hinge butts to which thehinges are pivoted, the hinge butts being secured to the transversehopper sheets.
